The strongest marks in the data are worth naming first: modeled tree cover settles in the top 5.7% nationally. Households without a vehicle rests at the national minimum, shared with about 16% of ZIPs. Modeled extreme heat lands at the national minimum, shared with about 19% of ZIPs. Modeled loud transportation noise settles at the national minimum, shared with about 22% of ZIPs. Modeled industrial-pollution burden rests in the bottom 11.7% nationally, homeownership lands in the top 12.4% nationally, and distance to a hazardous-chemical facility settles in the top 14.6% nationally. Modeled humid heat rests in the bottom 16% nationally, and transportation noise lands in the bottom 16% nationally. On the other side, distance to a nursing home settles in the top 15.0% nationally.

For context, industrial-pollution burden is the EPA's modeled screening score weighting industrial chemical releases by their toxicity and how many people live nearby. Distance to a hazardous-chemical facility is a plant handling large amounts of hazardous chemicals that must file an EPA risk-management plan for accidental releases. Extreme heat is a modeled count of days a year reaching a dangerously high temperature, a leading weather hazard. The closest ZIP that ranks healthier overall is ZIP 03280, just across the boundary.

Nearby & similar ZIPs

Editorially selected — see how this ZIP compares to nearby and similar places.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 1.29 years of 80.8, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match.
